Build constraints are commonly used to separate normal unit tests from integration tests that require external resources, like a database or network access. To do this, add a custom build constraint to the top of the test file:
// +build integration
package main
import (
"testing"
)
func TestThatRequiresNetworkAccess(t *testing.T) {
t.Fatal("It failed!")
}
The test file will not compile into the build executable unless the following invocation of go test
is used:
go test -tags "integration"
Results:
$ go test
? bitbucket.org/yourname/yourproject [no test files]
$ go test -tags "integration"
--- FAIL: TestThatRequiresNetworkAccess (0.00s)
